Hi, i am using the stape wordpress plugin and getting the following error repeatedly in my error log file:
PHP Warning: PHP Warning: Cannot modify header information - headers already sent in /home/xxxxx/public_html/wp-content/plugins/gtm-server-side/includes/class-gtm-server-side-helpers.php on line 300
Line 300 is setcookie(
Is there a way to fix this? I am getting the same error on all my sites using the stape plugin. Thanks.
